Service Connectivity Issues

Overview

Troubleshooting Kubernetes service connectivity problems.

Investigation Steps

1. Service Configuration

kubectl get svc {service_name} -n {namespace} -o yaml
kubectl get endpoints {service_name} -n {namespace}

2. Backend Pods

kubectl get pods -n {namespace} -l {selector}

3. Test Connectivity

kubectl run -it --rm debug --image=busybox --restart=Never -- wget -O- {service_name}:{port}

4. Network Policies

kubectl get networkpolicies -n {namespace}

Common Service Issues

• No endpoints (no matching pods)
• Selector mismatch
• Wrong target port
• Network policy blocking
• Service type misconfiguration
